Abstract: | Cultivation of mycorrhizal fungus,Lyophyllum shimeji, was examined using selected strains capable of forming primordia in pure culture. Mycelia grew fastest on barley grains containing synthetic liquid medium. The primordia readily formed in test-tubes after lowering the incubation temperature from 23°C to 15°C. The co-existence of pine seedlings had no promotive effect on primordium formation. Fruit-bodies formed on a medium consisting of barley, beech sawdust, and liquid synthetic nutrients in 500-ml glass bottles. Mature fruit-bodies produced basidiospores. The spores thus produced could germinate on an agar medium and formed mycelial colonies. Thereby, the life cycle inL. shimeji was accomplished in pure culture without using the host plant. |
